Five tonnes of bitumen spilled in Otara

Five tonnes of 140C bitumen have spilled from a factory tank
in Auckland this morning where authorities are working to
clean the hot mess.

Firefighters discovered the spill at Thermakraft Industries
on Turin Place in Otara after responding to an alarm about
9.50am.

The boiling bitumen covered an area about 15m by 25m inside
the factory and leaked to an area about 10m by 10m outside,
fire service communications shift manager Megan Ruru said.

"The fire service has attempted to contain the spill by
covering it with dirt," she said.

"We weren't told of any persons inside the building at the
time or whether any persons were hurt or injured.

"A check of the premises was done to confirm that the air
inside the building was within the safe exposure limits,
which it was, and then we've handed the scene over to the
Department of Labour, the city council and the building
owners."

It is not known what was inside the building or if any damage
was caused by the boiling bitumen.

Some of the spilled bitumen leaked into waterways before its
spread was stopped, Auckland City Council spokeswoman Lydia
Blatch said.

A pollution response officer from the council is at the
scene, where temporary containment barriers have been set up
to prevent further pollution reaching waterways.

Ms Blatch said the bitumen, which solidifies "reasonably
quickly", was believed to have been contained.

She said it was not known how much had reached the waterways.

"The company in question is working with council to clean up
the stream. Obviously the immediate attention is on
preventing any spread, which we've done by containing it," Ms
Blatch said.
